Helium will not react with carbon as helium is chemically inert.
helium (He)
Helium is converted into carbon during the final stage of fusion in a star called a red giant. This process occurs when helium fusion in the core of the star gives rise to carbon as the result of nuclear reactions.
Helium is converted to carbon in the final stage of fusion in stars like the Sun, which are considered to be medium-sized stars. This happens during the triple-alpha process where three helium nuclei combine to form a carbon nucleus.
Jupiter is formed from hydrogen and helium, it is a gas giant.
Helium fuses into carbon as the final stage in the life cycle of intermediate-mass stars, typically those with a mass between 0.8 to 8 times that of the Sun. This process occurs during the core helium burning phase when the star has exhausted its hydrogen fuel and evolved off the main sequence.
with water aswell it would become copper carbonate
Metallic oxides would not normally decompose as such. Most can be smelted with some form of carbon, in which case carbon monoxide or carbon dioxide is formed.
Helium is lighter than air, providing lift for airships. Carbon dioxide is denser than air, so it would not provide the necessary buoyancy. Additionally, helium is non-combustible, making it a safer choice for aviation.
People generally use helium in balloons because helium is lighter than the air in our atmosphere (mostly carbon dioxide and oxygen), so it floats. As opposed to filling it with oxygen or carbon dioxide, where it would just sink to the ground because it has the same weight as the air it is in.
The lightest weight element that is not a gas at room temperature is lithium. It is a solid metal with a low density and atomic number 3.
No, helium is not used in fire extinguishers. We find carbon dioxide (CO2) in some extinguishers, but not helium.
organic materials MUST contain carbon compounds, so Helium in a balloon would never be organic, for it does not contain carbon.(and Helium is pretty inert - so you couldn't easily make an organic compound with it anyway).
